Detailed explanation-1: -Raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is produced through the exchange of gases.

Detailed explanation-2: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-3: -The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf. Oxygen, a by-product of photosynthesis, and water vapor exit the leaf. In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem).

Detailed explanation-4: -Which of these is not a raw material for photosynthesis? The correct answer is option C-Oxygen. Oxygen is a by-product of photosynthesis and not a raw material used in the process. The raw materials used in photosynthesis include carbon dioxide, water, sunlight, and chlorophyll.

Detailed explanation-5: -Answer: Photosynthesis can be described as the process of transformation of light energy into chemical energy by green plants and some other organisms. The chemical equation is as follows: Carbondioxide Water Glucose water oxygen. More items
